SUMMARY

In the related art, however, it is difficult to install a portal which is an object for the avatar to move between virtual reality (VR) spaces. That is, the avatar is not easily movable between the VR spaces in the related art.

An information processing device as a first aspect of the present disclosure is an information processing device including: an installation instruction acceptance unit that accepts an installation instruction of a portal, which is an object for an avatar to move from a first VR space to a second VR space, in the first VR space, the installation instruction specifying the first VR space and the second VR space; and an installation processing unit that performs, in response to acceptance of the installation instruction, installation processing for installing the portal in the first VR space in one or more user terminals including another user terminal other than a user terminal that has accepted an input of the installation instruction.

Such a configuration makes it possible to install the portal which is the object for the avatar to move between the VR spaces. Therefore, the avatar can easily move between the VR spaces.

In addition, an information processing device as a second aspect of the present disclosure is the information processing device of the first aspect, in which the installation instruction includes first installation position information specifying the installation position of the portal in the first VR space and a second identifier specifying the second VR space.

With this configuration, an attribute value of the portal can be designated. Thus, for example, it is possible to arbitrarily set an installation position of the portal, a VR space as a movement destination, and the like, and it is possible to achieve VR experience with a higher degree of freedom for the user.

In addition, an information processing device as a third aspect of the present disclosure is the information processing device of the first or second aspect that further includes an installation determination unit that determines whether or not installation of the portal corresponding to the installation instruction satisfies an installation condition for installation of the portal, in which the installation processing unit performs the installation processing when the installation determination unit determines that the installation condition is satisfied.

With such a configuration, the portal can be installed when it is determined that the installation condition is satisfied. Thus, for example, it is possible to suppress unlimited creation of a portal that allows movement to a VR space in which only a specific user can originally participate, or the like.

In addition, an information processing device as a fourth aspect of the present disclosure is the information processing device of the third aspect, in which the installation condition is that a user corresponding to the installation instruction has installation authority, the installation determination unit determines whether or not the user corresponding to the installation instruction has the installation authority, and the installation processing unit performs the installation processing when the installation determination unit determines that the user has the installation authority.

With such a configuration, the portal can be installed when it is determined that an appropriate installation condition is satisfied. Thus, for example, only a specific user can install the portal, and as a result, it is possible to eliminate inconvenience such as unlimited installation of portals.

In addition, an information processing device as a fifth aspect of the present disclosure is the information processing device of any one of the first to fourth aspects that further includes: a movement determination unit that determines whether or not a movement condition for movement of the avatar based on the portal is satisfied; and a movement processing unit that performs movement processing which is processing of moving the avatar from the first VR space to the second VR space when the movement determination unit determines that the movement condition is satisfied.

With such a configuration, the avatar can move using the portal when it is determined that the movement condition is satisfied. Thus, the avatar can move using the portal when appropriate.

In addition, an information processing device as a sixth aspect of the present disclosure is the information processing device of the fifth aspect, in which the movement condition includes a distance condition based on a distance between the portal and the avatar, the movement determination unit determines whether or not the distance between the portal and the avatar is a distance that satisfies the distance condition, and the movement processing unit performs the movement processing when the movement determination unit determines that the distance condition is satisfied.

With such a configuration, the avatar can move using the portal when it is determined that an appropriate movement condition is satisfied. Thus, the user can suppress the avatar from unintentionally moving through the portal.

In addition, an information processing device as a seventh aspect of the present disclosure is the information processing device of the fifth or sixth aspect, in which the movement condition includes presence of a movement ticket corresponding to the avatar, and the movement processing is not performed when the movement determination unit determines that the movement ticket corresponding to the avatar is not present.

With such a configuration, the avatar can move using the portal when it is determined that an appropriate movement condition is satisfied.

In addition, an information processing device as an eighth aspect of the present disclosure is the information processing device of any one of the fifth to seventh aspects that further includes: a confirmation processing unit that performs confirmation processing for confirming whether or not to move from the first VR space to the second VR space, which correspond to the portal, when the avatar satisfies a predetermined confirmation condition; and a response acceptance unit that accepts a response corresponding to the confirmation processing, in which the movement processing unit performs movement processing which is processing of moving the avatar from the first VR space to the second VR space when the response accepted by the response acceptance unit is information indicating movement.

With such a configuration, the user can confirm whether or not to move when the avatar moves according to the present embodiment. Thus, the user can suppress the avatar from unintentionally moving through the portal.

In addition, an information processing device as a ninth aspect of the present disclosure is the information processing device of any one of the first to eighth aspects that further includes: a deletion determination unit that determines whether or not a deletion condition for deleting the portal is satisfied; and a deletion processing unit that performs deletion processing for deleting the portal for which the deletion determination unit has determined that the deletion condition is satisfied.

With this configuration, the portal can be automatically deleted. Thus, for example, only an appropriate portal can be left.

In addition, an information processing device as a tenth aspect of the present disclosure is the information processing device of the seventh aspect, in which the deletion condition is that one user has installed portals equal to or more than a threshold or more than the threshold, and the deletion processing unit deletes a portal installed by the user corresponding to the installation instruction accepted by the installation instruction acceptance unit, the portal being installed in the past.

With this configuration, the portal can be appropriately deleted. Thus, it is possible to reduce the possibility that a malicious user or the like installs a large number of portals to damage experience of other users in a VR space, and the like.

In addition, an information processing device as an eleventh aspect of the present disclosure is the information processing device of any one of the first to tenth aspects, in which the portal is the object that allows bidirectional movement including movement from the first VR space to the second VR space corresponding to the portal and movement from the second VR space to the first VR space.

With such a configuration, a bidirectional portal, which is an object for an avatar to move bidirectionally between two VR spaces, can be installed. Thus, the movement between VR spaces can be more easily performed since not only unidirectional movement but also bidirectional movement can be performed.

In addition, an information processing device as a twelfth aspect of the present disclosure is the information processing device of the eleventh aspect, in which the installation instruction has one or more pieces of position information of second installation position information specifying an installation position of the portal in the second VR space and first movement position information specifying an initial position in the first VR space when the avatar has moved to the first VR space based on the portal.

With this configuration, an attribute value of the bidirectional portal can be designated. Thus, for example, it is possible to arbitrarily set an installation position of the bidirectional portal, a VR space as a movement destination, and the like, and it is possible to easily achieve VR experience with a higher degree of freedom for the user.

In addition, an information processing device as a thirteenth aspect of the present disclosure is the information processing device of any one of the first to twelfth aspects that further includes: a portal storage unit that stores one or more pieces of portal information; and a terminal information storage unit that stores one or more pieces of terminal information related to the user terminals, in which the installation processing unit configures portal information corresponding to the installation instruction in response to the acceptance of the installation instruction, and performs portal registration processing of storing the portal information in the portal storage unit and portal arrangement processing of transmitting the portal information to the one or more user terminals respectively corresponding to the terminal information of the one or more pieces of terminal information stored in the terminal information storage unit.

With such a configuration, an installed portal can be reflected on another user terminal. Thus, it is possible to more easily move to an arbitrary VR space together with another user.

According to the information processing device of the present disclosure, it is possible to install the portal which is the object for the avatar to move between the VR spaces.

Note that the information system according to the present embodiment may be, for example, a system for supporting communication between users in a three-dimensional space in which two or more avatars that represent the respective users gather. Meanwhile, the information system is also applicable to games and the like. The information system only needs to have a function of outputting an avatar, and the application range thereof is not particularly limited.

FIG. 1 is a conceptual diagram of an information system A according to one or more aspects of the disclosed subject matter. The information system A includes an information processing device 1 and one or more user terminals 2.

The information processing device 1 is a server that receives an instruction from the user terminal 2 and transmits avatar information and portal information to the user terminal 2. The information processing device 1 is, for example, a cloud server, an Active Server Pages (ASP) server, or the like. Note that the type of the information processing device 1 is not particularly limited. In addition, the information processing device 1 may be a terminal as will be described later.

The user terminal 2 is a device that outputs an avatar or a portal. The user terminal 2 is, for example, a so-called personal computer, a tablet terminal, a smartphone, or the like, and the type thereof is not particularly limited.

The information processing device 1 can communicate with each of the one or more user terminals 2 through a communication line such as the Internet.

FIG. 2 is a block diagram of the information system A according to one or more aspects of the disclosed subject matter. The information processing device 1 includes a storage unit 11, an acceptance unit 12, a processing unit 13, and a transmission unit 14. The storage unit 11 includes a terminal information storage unit 111, a world storage unit 112, an avatar storage unit 113, and a portal storage unit 114. The acceptance unit 12 includes an installation instruction acceptance unit 121 and a response acceptance unit 122. The processing unit 13 includes an installation determination unit 131, an installation processing unit 132, a deletion determination unit 133, a deletion processing unit 134, a confirmation processing unit 135, a movement determination unit 136, and a movement processing unit 137.

The user terminal 2 includes a terminal storage unit 21, a terminal acceptance unit 22, a terminal processing unit 23, a terminal transmission unit 24, a terminal reception unit 25, and a terminal output unit 26.

The storage unit 11 constituting the information processing device 1 stores various types of information. The various types of information are, for example, terminal information to be described later, world information to be described later, avatar information to be described later, portal information to be described later, an installation condition to be described later, a deletion condition to be described later, a confirmation condition to be described later, a movement condition to be described later, and a movement ticket to be described later.

The terminal information storage unit 111 stores one or more pieces of terminal information. The terminal information is information related to the user terminal 2. The terminal information may be information related to a user who uses the user terminal 2. The terminal information may be information related to an avatar corresponding to the user who uses the user terminal 2. The terminal information includes, for example, a terminal identifier, a world identifier, and an avatar identifier. The terminal information may have, for example, the installation condition to be described later, the deletion condition to be described later, the confirmation condition to be described later, and the movement condition to be described later. That is, the installation condition, the deletion condition, the confirmation condition, and the movement condition may be different for each of the user terminals 2. Being different for each of the user terminals 2 means being different for each user or being different for each avatar. The terminal information has, for example, installation authority to be described later. In addition, the installation condition, the deletion condition, the confirmation condition, and the movement condition may be common to all the user terminals 2, all the users, and all the avatars.

The terminal identifier is information for identifying the user terminal 2. The terminal identifier is, for example, an ID, information (for example, an IP address or a telephone number) for communicating with the user terminal 2, a mail address, or a telephone number. The world identifier is information for identifying a world. The world identifier is, for example, an ID. The avatar identifier is information for identifying an avatar. The avatar identifier is, for example, an ID.

Note that the world identifier included in the terminal information is information for identifying a world that is being currently output on the corresponding user terminal 2. In addition, the avatar included in the terminal information is an avatar corresponding to a user who uses the corresponding user terminal 2. Note that the avatar may be referred to as a character. Needless to say, a shape, an outer shape, and the like of the avatar are not particularly limited.

The world storage unit 112 stores one or more pieces of world information. The world information is information for configuring a world. The structure of the world information is not particularly limited. The world is generally a virtual three-dimensional space. Note that the world may be referred to as a field. The world information is associated with, for example, a world identifier. Here, the world information is information configuring two or more VR spaces. The structure of the world information is not particularly limited.

The avatar storage unit 113 stores one or more pieces of avatar information. The avatar information includes information for configuring an avatar to be output. The avatar information is associated with, for example, an avatar identifier. Associating with the avatar identifier may mean having the avatar identifier. The avatar identifier is, for example, an ID of an avatar, but may be an ID of a user corresponding to the avatar, an ID of the user terminal 2 on which the avatar is to be displayed, or the like.

The avatar information generally includes model information. The avatar information preferably has avatar motion information that is information on a motion of the avatar.

The model information is information for configuring the display of the avatar. The model information includes, for example, mesh information, bone information, and material information. The model information has, for example, a data structure of glTF (GL Transmission Format). However, the data structure of the model information may be VRM, OBJ, FBX, STL, GLB, COLLADA, or the like, and may be of any type. The avatar information may include voice information and one or more attribute values in addition to the model information.

The avatar motion information is, for example, information specifying a motion when the avatar breathes. The avatar motion information is information of a fixed motion of the avatar.

The portal storage unit 114 stores one or more pieces of portal information. The portal information is information related to a portal. The portal is an object for the avatar to move between two VR spaces. The portal serves as a so-called virtual door. The portal is, for example, a unidirectional portal. The unidirectional portal is an object that allows an avatar to move from a first VR space to a second VR space, but does not allow the avatar to move from the second VR space to the first VR space. In a case where the portal is the unidirectional portal, the first VR space is a VR space as a movement source, and the second VR space is a VR space as a movement destination. Note that the portal may be the unidirectional portal or a bidirectional portal. The bidirectional portal is a portal through which an avatar is movable bidirectionally. Being movable bidirectionally means that being movable from the first VR space to the second VR space and being also movable from the second VR space to the first VR space.

The portal information is information associated with a portal identifier. The portal identifier is information for identifying a portal, and is, for example, an ID. The portal information is preferably associated with a terminal identifier of the user terminal 2 that has transmitted an installation instruction. Being associated with the terminal identifier may be being associated with a user identifier or being associated with an avatar identifier.

The portal information has one or more portal attribute values. The one or more portal attribute values are, for example, a first identifier specifying the first VR space, a second identifier specifying the second VR space, first installation position information, and second movement position information.

The first installation position information is information specifying an installation position of a portal in the first VR space. The first installation position information is, for example, a set of relative three-dimensional coordinates in the first VR space and eight three-dimensional coordinates for specifying a rectangular parallelepiped region in the first VR space.

The second movement position information is information specifying an initial position in the second VR space in a case where an avatar moves from the first VR space to the second VR space on the basis of a portal. The second movement position information is, for example, a set of relative three-dimensional coordinates in the second VR space and eight three-dimensional coordinates for specifying a rectangular parallelepiped region in the second VR space. Note that, in a case where portal information includes no first installation position information, a portal corresponding to this portal information is arranged at a default position in the first VR space. In addition, in a case where portal information includes no second movement position information and an avatar moves from the first VR space to the second VR space using a portal corresponding to this portal information, an initial position of an avatar after the movement is a default position in the second VR space.

In a case where the portal is the bidirectional portal, second installation position information and first movement position information may be included in one or more portal attribute values included in portal information. The second installation position information is information specifying an installation position of the portal in the second VR space. The first movement position information is information specifying an initial position in the first VR space in a case where an avatar moves from the second VR space to the first VR space on the basis of the portal. The first movement position information is, for example, a set of relative three-dimensional coordinates in the first VR space and eight three-dimensional coordinates for specifying a rectangular parallelepiped region in the first VR space.

Note that, in a case where the portal is the bidirectional portal and the portal information includes no second installation position information, the portal corresponding to this portal information is arranged at a default position in the second VR space. In addition, in a case where the portal is the bidirectional portal, the portal information includes no first movement position information, and an avatar has moved from the second VR space to the first VR space using the portal corresponding to this portal information, an initial position of the avatar after the movement is a default position in the first VR space.

In addition, in the case where the portal is the bidirectional portal, a position specified by the first movement position information and a position specified by the first installation position information may be the same. In addition, in the case where the portal is the bidirectional portal, a position specified by the second movement position information and a position specified by the second installation position information may be the same.

The acceptance unit 12 receives various types of instructions and information. The various types of instructions and information are, for example, installation instructions to be described later, responses to be described later, and operation information.

The operation information is information related to an operation of a user. The operation information is received from the user terminal 2, for example. The operation information is, for example, a command given to an avatar and position information indicating a position to which the avatar moves. The operation information may have any structure, content, and the like.

The acceptance unit 12 receives, for example, various types of instructions and information from the user terminal 2. That is, the acceptance here is the acceptance of information transmitted via the wired or wireless communication line, but may be a concept including acceptance of information input from an input device such as a keyboard, a mouse, or a touch panel, acceptance of information read from a recording medium such as an optical disk, a magnetic disk, or a semiconductor memory, and the like.

The installation instruction acceptance unit 121 accepts an installation instruction. The installation instruction acceptance unit 121 receives the installation instruction, for example, from the user terminal 2. For example, the installation instruction acceptance unit 121 may accept the installation instruction input by a user.

The installation instruction is an instruction to install a portal in a first VR space. Through the installation instruction, the first VR space in which the portal is to be installed and a second VR space as a movement destination are specified. The installation instruction of the unidirectional portal includes, for example, one or more pieces of information of a first identifier, a second identifier, first installation position information, and second movement position information. The installation instruction of the bidirectional portal includes, for example, one or more pieces of information of a first identifier, a second identifier, first installation position information, second installation position information, first movement position information, and second movement position information.

The response acceptance unit 122 accepts a response corresponding to confirmation processing. The response acceptance unit 122 receives the response, for example, from the user terminal 2.

The confirmation processing is processing for confirming whether or not an avatar moves. The confirmation processing is, for example, processing for confirming whether or not the avatar moves from a first VR space to a second VR space which correspond to a portal. In a case where the portal is a bidirectional portal, the confirmation processing is, for example, processing for confirming whether or not the avatar moves from the second VR space to the first VR space which correspond to the portal. The confirmation processing is, for example, processing of transmitting, to the user terminal 2, information, screen information, or the like for inquiring whether or not to move the avatar.

The response is information specifying whether or not to move. The response is, for example, a flag that can take any one of information indicating movement (for example, “1”) and information indicating non-movement (for example, “0”).

The processing unit 13 performs various types of processing. The various types of processing are, for example, processing performed by each of the installation determination unit 131, the installation processing unit 132, the deletion determination unit 133, the deletion processing unit 134, the confirmation processing unit 135, the movement determination unit 136, and the movement processing unit 137.

The installation determination unit 131 determines whether or not installation of a portal corresponding to an installation instruction satisfies the installation condition.

The installation condition is a condition for installing a portal. The installation condition is, for example, a condition related to an authority of a user and a condition related to the number of installed portals. The installation condition is, for example, that a user corresponding to an installation instruction has installation authority. The installation condition is, for example, that there is no portal for movement from a first VR space corresponding to an installation instruction to a second VR space corresponding to the installation instruction; that the number of portals installed by a particular user is equal to or less than a threshold or less than the threshold; that the number of portals that have been installed by a particular user in a particular world is equal to or less than a threshold or less than the threshold; that the number of portals for movement from a first VR space corresponding to an installation instruction to a second VR space corresponding to the installation instruction is equal to or less than a threshold or less than the threshold; or that the number of portals that have been already installed in a first VR space corresponding to an installation instruction is equal to or less than a threshold or less than the threshold.

Note that the installation authority paired with the user is installation authority possessed by terminal information corresponding to the user. The installation authority is information indicating presence of authority required in the case of installing a portal. That is, the installation determination unit 131 preferably determines whether the installation authority is stored in association with the terminal information of the user corresponding to the installation instruction. In addition, the installation authority may be authority to participate in a first VR space and a second VR space specified from identifiers included in the installation instruction. In a case where the user has the authority to participate in both the first VR space and the second VR space, it may be regarded that the user has the installation authority to the portal.

Note that the installation authority is generally stored in the storage unit 11, but may be stored in another device.

The installation processing unit 132 performs installation processing for installing a portal in a first VR space in one or more devices including a device receiving an input of an installation instruction and another device other than the device. The device receiving the input of the installation instruction is generally the user terminal 2. In addition, the another device is generally another user terminal 2. However, the device receiving the input of the installation instruction and the another device may be the information processing devices 1 suitable for information operating in a peer-to-peer (P2P) manner. The installation processing unit 132 performs the installation processing for installing a portal in a first VR space, for example, in one or more user terminals 2.

The installation processing is generally processing for installing a portal corresponding to an installation instruction. The installation processing includes, for example, portal registration processing and portal arrangement processing. Note that the installed portal may also use an avatar of a user other than a user who has installed the portal to move from a first VR space corresponding to the portal to a second VR space.

The portal registration processing is processing of configuring portal information corresponding to an installation instruction in response to acceptance of the installation instruction and storing the portal information in the portal storage unit 114.

The portal arrangement processing is processing of configuring portal information having a second identifier corresponding to an installation instruction in response to acceptance of the installation instruction, and transmitting the portal information to one or more user terminals 2. The one or more user terminals 2 generally include another user terminal 2 different from one user terminal 2 that has transmitted the installation instruction. The one or more user terminals 2 preferably include the one user terminal 2 that has transmitted the installation instruction.

The installation processing unit 132 performs the installation processing, for example, when the installation determination unit 131 determines that the installation condition is satisfied.

The installation processing unit 132 performs the installation processing, for example, when the installation determination unit 131 determines that installation authority corresponding to the one user terminal 2 that has transmitted the installation instruction is stored.

The deletion determination unit 133 determines whether or not a deletion condition is satisfied. For example, the deletion determination unit 133 determines whether or not the deletion condition is satisfied in response to acceptance of an installation instruction by the installation instruction acceptance unit 121. For example, the deletion determination unit 133 periodically determines whether or not the deletion condition is satisfied. That is, a trigger of the operation of the deletion determination unit 133 is not particularly limited.

The deletion condition is a condition for deleting a portal. The deletion condition is, for example, a condition related to the number of portals. The deletion condition is, for example, a condition related to use frequency.

The deletion condition related to the number of portals is, for example, that one user has installed portals equal to or more than a threshold or more than the threshold, or that there are portals equal to or more than a threshold or more than the threshold in a first VR space in which a portal has been installed.

The condition related to the use frequency is, for example, that the use frequency is low enough to satisfy the condition. The condition related to the use frequency is, for example, that movement of an avatar using a portal for a unit period is equal to or less than a threshold or less than the threshold. The condition regarding the use frequency is, for example, that movement of an avatar using a portal so far is equal to or less than a threshold or less than the threshold.

The deletion processing unit 134 performs the deletion processing for deleting a portal for which the deletion determination unit 133 has determined that the deletion condition is satisfied. The deletion processing is, for example, processing of deleting portal information from the portal storage unit 114. The deletion processing is, for example, transmitting a deletion instruction to each of one or more user terminals 2 in which the portal is installed. The deletion instruction includes, for example, information (for example, a portal identifier or the portal information itself) for specifying the portal information to be deleted.

The deletion processing unit 134 deletes, for example, a portal installed in the past, the portal installed by a user corresponding to an installation instruction received by the installation instruction acceptance unit 121.

In a case where an avatar satisfies a predetermined confirmation condition, the confirmation processing unit 135 performs confirmation processing corresponding to a portal. The confirmation condition is a condition for causing a user to confirm whether or not to move the avatar via the portal. Note that the confirmation condition may be the same as the movement condition to be described later.

The confirmation processing is processing for confirming whether or not to move from a first VR space to a second VR space which correspond to the portal. The confirmation processing may be, for example, processing for confirming whether or not to move from the second VR space to the first VR space which correspond to the portal. The confirmation processing is, for example, processing of transmitting screen information for confirmation to the user terminal 2.

The movement determination unit 136 determines whether or not the movement condition is satisfied. The movement condition is a condition for determining whether or not to move an avatar via a portal. The movement condition is, for example, a distance condition or a ticket condition.

The distance condition is a condition related to a distance between a portal and an avatar. The distance condition is, for example, that a distance between the portal and the avatar is equal to or less than a threshold or less than the threshold. In addition, the distance condition is, for example, that the avatar has come into contact with the portal (that is, the distance is zero).

The ticket condition is that an avatar has a movement ticket. The condition that the avatar has the movement ticket may be a condition that the user terminal 2 or a user corresponding to the avatar has the movement ticket. The condition that the avatar has the movement ticket means that, for example, terminal information corresponding to the user terminal 2 has the movement ticket. Note that the movement ticket is information required for movement from a first VR space to a second VR space. The movement ticket has, for example, a second identifier for identifying the second VR space as a movement destination. The movement ticket has, for example, a second identifier for identifying a first VR space as a movement source. The movement ticket includes, for example, number-of-times information specifying the number of times movement is possible. In a case where the movement ticket has the number-of-times information, the number-of-times information in the movement ticket decreases every movement, and the movement ticket is no longer usable when the number-of-times information becomes zero.

For example, the movement determination unit 136 determines whether or not a distance between a portal and an avatar is small enough to satisfy the distance condition.

The movement processing unit 137 performs movement processing using a portal. The movement processing is processing of moving an avatar to a second VR space corresponding to the portal. In the movement processing, for example, second movement position information specifying an initial position in the second VR space corresponding to the portal is set as position information of the avatar. Then, the movement processing unit 137 transmits a movement instruction including an avatar identifier for identifying the avatar, a second identifier, and the second movement position information to each of one or more user terminals 2 such that the position of the avatar is change to a position indicated by the second movement position information in the second VR space, for example. Note that the movement instruction is an instruction to move the avatar.

The movement processing unit 137 performs the movement processing when the movement determination unit 136 determines that the movement condition is satisfied.

The movement processing unit 137 does not perform the movement processing when the movement determination unit 136 determines that the distance condition is not satisfied.

In a case where a response accepted by the response acceptance unit 122 is information indicating movement, the movement processing unit 137 performs the movement processing that is processing of moving an avatar from a first VR space to a second VR space. On the other hand, in a case where the response accepted by the response acceptance unit 122 is information indicating non-movement, the movement processing unit 137 does not perform the movement processing.

The transmission unit 14 transmits various instructions and information to one or more user terminals 2. The various instructions and information are, for example, world information, avatar information, and portal information.

The terminal storage unit 21 constituting the user terminal 2 stores various types of information. The various types of information are, for example, world information, avatar information, and portal information. The various types of information are generally information received from the information processing device 1. However, the world information and the like may be information received from another user terminal 2 or a device (not illustrated).

The terminal acceptance unit 22 accepts various types of information, instructions, and operations. Note that the instruction may be considered to include an operation. In addition, the various types of information, instructions, and operations are, for example, an output instruction, an installation instruction, and a response. The output instruction is an instruction to output a virtual three-dimensional image including an avatar. The output instruction has, for example, an avatar identifier for identifying the avatar to be used, and a world identifier for identifying a world to be used.

Here, the acceptance is generally acceptance of information input from input means, but may be a concept including, for example, acceptance of information transmitted via a wired or wireless communication line, and acceptance of information read from a recording medium such as an optical disk, a magnetic disk, or a semiconductor memory. Note that the input means may be, for example, various input means for VR and games, a mouse, a keyboard, a cross key, or the like. The input means for VR or games are, for example, a hand controller and the PHANToM.

The terminal processing unit 23 performs various types of processing. In the various types of processing, for example, one or more pieces of information among world information, avatar information, and portal information are used to configure an image to be output. Such an image is generally a virtual three-dimensional image and has an avatar. Such an image generally has one or more VR spaces. Such an image preferably has a portal. Such an image preferably has a world. In addition, the image is generally a moving image having a motion corresponding to an operation accepted by the terminal acceptance unit 22. The various types of processing are, for example, processing of operating an avatar on the basis of the operation accepted by the terminal acceptance unit 22. In the various types of processing, for example, a screen is configured using received screen information.

The terminal processing unit 23 configures operation information in accordance with an operation accepted by the terminal acceptance unit 22 from a user. The terminal processing unit 23 configures an image having an avatar, a world, or the like that changes in accordance with the operation accepted by the terminal acceptance unit 22 from the user.

The terminal processing unit 23 configures an instruction or information to be transmitted, for example, using an instruction or information accepted by the terminal acceptance unit 22.

The terminal transmission unit 24 transmits various instructions and information to the information processing device 1. The various instructions and information are, for example, an output instruction, an installation instruction, a response, and operation information.

The terminal reception unit 25 receives various instructions and information from the information processing device 1. The various instructions and information are, for example, world information, avatar information, portal information, screen information, and a confirmation instruction.

The terminal output unit 26 outputs various types of information. The various types of information are, for example, an image configured by the terminal processing unit 23 and a screen for receiving an input of a response.

Here, the output is generally display on a display and projection using a projector, but may be a concept including, for example, storage in a recording medium, and delivery of a processing result to another processing device, another program, or the like.

The storage unit 11, the terminal information storage unit 111, the world storage unit 112, the avatar storage unit 113, the portal storage unit 114, and the terminal storage unit 21 are preferably volatile recording media, but can also be achieved by non-volatile recording media. The process of storing information in the storage unit 11 or the like is not particularly limited. For example, information may be stored in the storage unit 11 or the like via a recording medium, information transmitted via a communication line or the like may be stored in the storage unit 11 or the like, or information input via an input device may be stored in the storage unit 11 or the like.

The acceptance unit 12, the installation instruction acceptance unit 121, the response acceptance unit 122, and the terminal reception unit 25 are generally achieved by wireless or wired communication means, but may be achieved by means for receiving broadcast.

The processing unit 13, the installation determination unit 131, the installation processing unit 132, the deletion determination unit 133, the deletion processing unit 134, the confirmation processing unit 135, the movement determination unit 136, the movement processing unit 137, and the terminal processing unit 23 can be generally achieved by a processor, a memory, and the like. The procedure of the processing performed by the processing unit 13 and the like is generally achieved by software, and the software is recorded in a recording medium such as a read-only memory (ROM). However, it may be achieved by hardware (dedicated circuit). Note that the processor is a central processing unit (CPU), a micro-processing unit (MPU), a graphics processing unit (GPU), or the like, and the type of the processing unit is not particularly limited. Further, processors are considered processing circuitry or circuitry as they include transistors and other circuitry therein. The processor may be a programmed processor which executes a program stored in a memory. In the disclosure, the circuitry, units, or means are hardware that carry out or are programmed to perform the recited functionality. The hardware may be any hardware disclosed herein or otherwise known which is programmed or configured to carry out the recited functionality. When the hardware is a processor which may be considered a type of circuitry, the circuitry, means, or units are a combination of hardware and software, the software being used to configure the hardware and/or processor.

The transmission unit 14 and the terminal transmission unit 24 are generally achieved by wireless or wired communication means, but may be achieved by broadcasting means.

The terminal acceptance unit 22 can be achieved by a device driver of input means such as a touch panel or a keyboard, control software of a menu screen, or the like.

The terminal output unit 26 may be considered to include or not include an output device such as a display. The terminal output unit 26 can be achieved by driver software of an output device, or driver software of an output device and the output device together.

Next, an operation example of the information system A will be described. First, an operation example of the information processing device 1 will be described with reference to a flowchart of FIG. 3 .

(Step S301) The acceptance unit 12 determines whether or not an output instruction has been received from the user terminal 2. The process proceeds to step S302 when the output instruction has been received, and proceeds to step S304 when the output instruction has not been received.

(Step S302) The processing unit 13 acquires world information, which corresponds to the user terminal 2 that has transmitted the output instruction, from the world storage unit 112. The processing unit 13 acquires avatar information corresponding to the user terminal 2 from the avatar storage unit 113. The processing unit 13 acquires one or more pieces of portal information corresponding to the user terminal 2 from the portal storage unit 114.

Note that the processing unit 13 may acquire world information, identified by a world identifier included in the output instruction, from the world storage unit 112, acquire portal information of a portal in the corresponding world from the portal storage unit 114, and acquire avatar information, identified by an avatar identifier included in the output instruction, from the avatar storage unit 113.

Here, the processing unit 13 may use the acquired world information, avatar information, and one or more pieces of portal information to configure an output image to be output by the user terminal 2 that has transmitted the output instruction.

(Step S303) The transmission unit 14 transmits the world information, the avatar information, and the one or more pieces of portal information, which have been acquired in step S302, to the user terminal 2 that has transmitted the output instruction. The process returns to step S301.

In a case where the output image is configured in step S302, the transmission unit 14 transmits the output image to the user terminal 2.

(Step S304) The installation instruction acceptance unit 121 determines whether or not an installation instruction has been received from the user terminal 2. The process proceeds to step S305 when the installation instruction has been received, and proceeds to step S308 when the installation instruction has not been received.

(Step S305) The processing unit 13 performs portal installation processing. An example of the installation processing will be described with reference to a flowchart of FIG. 4 .

(Step S306) In step S305, the deletion determination unit 133 determines whether or not a portal has been installed. The process proceeds to step S307 when the portal has been installed, and returns to step S301 when the portal has not been installed.

(Step S307) The processing unit 13 performs portal deletion processing. An example of the deletion processing will be described with reference to a flowchart of FIG. 5 . The process returns to step S301. Here, the portal deletion is not necessarily performed.

(Step S308) The acceptance unit 12 determines whether or not operation information has been received from the user terminal 2. The process proceeds to step S309 when the operation information has been received, and returns to step S301 when the operation information has not been received.

(Step S309) The movement determination unit 136 determines whether or not a movement condition is satisfied using the operation information received in step S308. The process proceeds to step S310 when the movement condition is satisfied, and proceeds to step S316 when the movement condition is not satisfied.

(Step S310) The confirmation processing unit 135 determines whether or not to confirm whether to perform the movement processing. The process proceeds to step S311 when the confirmation is to be performed, and proceeds to step S314 when the confirmation is not to be performed.

Note that the confirmation processing unit 135 may determine to constantly confirm whether to perform the movement processing, may determine not to constantly confirm whether to perform the movement processing, may determine whether or not to perform confirmation using a common confirmation condition, or may determine whether to perform confirmation by referring to a confirmation condition stored in association with avatar information or terminal information.

(Step S311) The confirmation processing unit 135 acquires screen information for the confirmation from the storage unit 11, and transmits the screen information to the user terminal 2 that has transmitted the installation instruction.

(Step S312) The response acceptance unit 122 determines whether or not a response has been received from the user terminal 2. The process proceeds to step S313 when the response has been received, and returns to step S312 when the response has not been received.

(Step S313) The process proceeds to step S314 when the response that has been received in step S312 is a response of “move”, and proceeds to step S316 when the response is a response of “not move”.

(Step S314) The movement processing unit 137 acquires a second identifier and second movement position information, included in portal information corresponding to the operation information received in step S308, from the portal storage unit 114.

The process returns to step S301.

Note that the processing of moving the avatar is, for example, processing of transmitting an avatar identifier, the second identifier, and the second movement position information of the avatar to be moved to one or more user terminals 2. In addition, the processing of moving the avatar is, for example, processing of rewriting a world identifier for specifying a world in which the avatar exists as the second identifier.

(Step S316) The processing unit 13 acquires information corresponding to the operation information received in step S308. The information corresponding to the operation information is, for example, information for moving an avatar, and is, for example, an avatar identifier and position information of the avatar after movement. The information corresponding to the operation information is, for example, information for creating a motion of an avatar, and is, for example, an avatar identifier and action information for creating the motion. However, the information corresponding to the operation information may have various types, and is not particularly limited.

(Step S317) The processing unit 13 transmits the information acquired in step S316 to one or more user terminals 2. The process returns to step S301. Note that a process of causing another user terminal 2 to perform a motion of an avatar by using operation information corresponding to an operation on the avatar performed on one user terminal 2 is a publicly known technique, and thus a detailed description thereof will be omitted.

Note that the deletion processing is performed after the installation processing in the flowchart of FIG. 3 . However, the trigger of the deletion processing is not particularly limited.

Note that the process ends due to power-off and/or an interruption ending the process in the flowchart of FIG. 3 .

The process proceeds to step S412 when there is the i-th terminal information, and returns to the upper routine when there is no i-th terminal information.

(Step S412) The installation processing unit 132 determines whether or not to transmit the portal information configured in step S408 to the user terminal 2 corresponding to the i-th terminal information. The process proceeds to step S413 when the portal information is to be transmitted, and proceeds to step S414 when the portal information is not to be transmitted.

Note that the installation processing unit 132 determines to transmit the portal information, for example, in a case where the i-th terminal information has a movement ticket that allows use of a portal. In addition, the installation processing unit 132 determines to transmit the portal information, for example, in a case where a world identifier included in the portal information coincides with a world identifier for identifying a world in which an avatar corresponding to the i-th terminal information exists. Note that a condition for determining the user terminal 2 to which the portal information is to be transmitted is not particularly limited.

(Step S413) The installation processing unit 132 transmits the portal information configured in step S408 to the user terminal 2 corresponding to the i-th terminal information.

(Step S414) The installation processing unit 132 increments the counter i by 1. The process returns to step S411.

Next, an example of the deletion processing in step S307 will be described with reference to the flowchart of FIG. 5 .

(Step S501) The deletion determination unit 133 substitutes 1 into the counter i.

(Step S502) The deletion determination unit 133 determines whether or not there is an i-th deletion condition in the storage unit 11. The process proceeds to step S503 when there is the i-th deletion condition, and proceeds to step S507 when there is no i-th deletion condition.

(Step S503) The deletion determination unit 133 refers to the portal storage unit 114 and determines portal information matching the i-th deletion condition.

(Step S504) In step S503, the deletion processing unit 134 determines whether or not there are one or more pieces of portal information determined to be deleted. The process proceeds to step S505 when there is the portal information to be deleted, and proceeds to step S506 when there is no portal information to be deleted.

(Step S505) The deletion processing unit 134 deletes the one or more pieces of portal information determined in step S503 from the portal storage unit 114.

(Step S506) The deletion determination unit 133 increments the counter i by 1. The process returns to step S502.

(Step S507) The deletion processing unit 134 performs deletion notification processing. The process returns to the upper routine. Note that the deletion notification processing is processing of notifying the user terminal 2 of the portal information to be deleted. An example of the deletion notification processing will be described with reference to a flowchart of FIG. 6 .

The process proceeds to step S606 when the notification of the deletion is to be made, and proceeds to step S607 when the notification of the deletion is not to be made. Note that the deletion processing unit 134 generally determines to notify the user terminal 2 transmitting the i-th portal information of the deletion.

(Step S606) The deletion processing unit 134 transmits a portal deletion instruction including information specifying the i-th portal information (for example, a portal identifier or portal information) to the user terminal 2 corresponding to the j-th terminal information.

(Step S607) The deletion determination unit 133 increments the counter j by 1. The process returns to step S604.

(Step S608) The deletion determination unit 133 increments the counter i by 1. The process returns to step S602.

The process proceeds to step S702 when the output instruction has been accepted, and proceeds to step S707 when the output instruction has not been accepted. Note that the output instruction includes, for example, a world identifier and an avatar identifier.

(Step S702) The terminal processing unit 23 acquires a terminal identifier of the terminal storage unit 21, and configures an output instruction having the terminal identifier. The terminal transmission unit 24 transmits the output instruction to the information processing device 1.

(Step S710) The terminal processing unit 23 determines whether or not the information received in step S709 is portal information. The process proceeds to step S711 in the case of the portal information, and proceeds to step S712 in the case of an error message.

(Step S711) The terminal processing unit 23 stores the portal information received in step S709 in the terminal storage unit 21.

(Step S713) The terminal acceptance unit 22 determines whether or not an operation from a user has been accepted. The process proceeds to step S714 when the operation has been accepted, and proceeds to step S717 when the operation has not been accepted.

(Step S714) The terminal processing unit 23 configures information to be changed in accordance with the operation in step S713. The terminal output unit 26 outputs the configured information. Note that the information to be changed is, for example, information of an avatar whose posture has been changed, information of an avatar whose position has been changed, or the like.

(Step S715) The terminal processing unit 23 configures operation information in accordance with the operation in step S713. Note that the terminal processing unit 23 generally acquires a terminal identifier of the terminal storage unit 21 and configures operation information associated with the terminal identifier.

(Step S716) The terminal transmission unit 24 transmits the operation information associated with the terminal identifier to the information processing device 1. The process returns to step S701. Step S717 and the subsequent steps are illustrated in FIG. 8 .

(Step S718) The terminal processing unit 23 configures confirmation information to be output. The terminal output unit 26 outputs the confirmation information.

(Step S719) The terminal acceptance unit 22 determines whether or not a response from the user has been accepted. The process proceeds to step S720 when the response has been accepted, and returns to step S719 when the response has not been accepted.

(Step S720) The terminal processing unit 23 uses the response accepted in step S719 to configure a response to be transmitted. Note that the terminal processing unit 23 acquires, for example, a portal identifier or a terminal identifier corresponding to the confirmation information, and configures a response associated with the portal identifier or the terminal identifier. The terminal transmission unit 24 transmits the response associated with the portal identifier or the terminal identifier to the information processing device 1.

(Step S721) The terminal processing unit 23 determines whether or not the response accepted in step S719 is a response of “move”. The process proceeds to step S722 in the case of the response of “move”, and returns to step S701 in the case of a response of “not move”.

(Step S722) The terminal processing unit 23 performs processing of moving an avatar to a position specified by second position information in a second VR space identified by a second identifier corresponding to a portal corresponding to the confirmation information. The process returns to step S701. Note that an output in which the avatar corresponding to the user terminal 2 moves from a current position in a first VR space to the position specified by the second position information in the second VR space can be obtained by the processing of moving the avatar.

(Step S723) The terminal reception unit 25 determines whether or not portal information has been received. The process proceeds to step S724 when the portal information has been received, and proceeds to step S726 when the portal information has not been received.

(Step S724) The terminal processing unit 23 stores the portal information received in step S723 in the terminal storage unit 21.

(Step S725) the terminal processing unit 23 uses the portal information received in step S723 to configure a portal to be output. The terminal output unit 26 outputs the portal onto a VR space. The process returns to step S701.

(Step S726) The terminal reception unit 25 determines whether or not a portal deletion instruction has been received. The process proceeds to step S727 when the deletion instruction has been received, and proceeds to step S728 when the deletion instruction has not been received.

(Step S727) The terminal processing unit 23 deletes portal information, which corresponds to the deletion instruction received in step S726, from the terminal storage unit 21. In addition, the terminal processing unit 23 configures an output image that hides a portal corresponding to the deletion instruction not to be displayed. Then, the terminal output unit 26 hides the portal not to be displayed. The process returns to step S701.

(Step S728) The terminal reception unit 25 determines whether or not information on another avatar has been received. The process proceeds to step S729 when the information on the another avatar has been received, and returns to step S701 when the information on the another avatar has not been received.

(Step S729) The terminal processing unit 23 performs processing of changing an output of the another avatar using the information on the another avatar received in step S728. The terminal output unit 26 changes the output of the another avatar. The process returns to step S701. Note that the processing of changing the output of the another avatar using the information on the another avatar is a known technique.

Note that the user terminal 2 outputs the portal into the world by using the portal information received from the information processing device 1 after transmitting the installation instruction in the flowchart of FIG. 7 . However, the user terminal 2 may output the portal into the world in response to the received installation instruction, and then, transmit the portal information of the installed portal to the information processing device 1. The process of processing until a portal according to an installation instruction input by one user is installed in one or more user terminals 2 is not particularly limited.

Note that the process ends due to power-off and/or an interruption ending the process in the flowcharts of FIGS. 7 and 8 .

Hereinafter, a specific operation example of the information system A according to the present embodiment will be described.

Here, it is assumed that the terminal information storage unit 111 of the information processing device 1 stores a terminal information management table having a structure illustrated in FIG. 9 . The terminal information management table is a table that manages terminal information. The terminal information management table manages one or more records having a “terminal identifier”, a “world identifier”, an “avatar identifier”, an “installation condition”, a “deletion condition”, a “confirmation condition”, and a “movement condition”. The “terminal identifier” is information for identifying the user terminal 2. The “world identifier” is information for identifying a world output on the user terminal 2. The “avatar identifier” is information for identifying an avatar corresponding to a user who uses the user terminal 2. The “installation condition (installation authority)” is a condition for the user (avatar) who uses the user terminal 2 to install a portal, and here, is information indicating whether or not the user has authority to install the portal. An attribute value “1” of the “installation condition (installation authority)” means that the user has the installation authority, and an attribute value “0” means that the user does not have the installation authority. Here, the “deletion condition” is a condition for deleting a portal installed in the past in a case where the user installed the portal. An attribute value “2 or less” of the “deletion condition” indicates that the user can install up to two portals, and means that a portal whose installation date and time is the oldest, the portal having been installed by the same user, is deleted in a case where the third portal has been installed. An attribute value “maximum 1” of the “deletion condition” indicates that the user can install only one portal, and means that a portal whose installation date and time is the oldest, the portal having been installed by the same user, is deleted in a case where the second portal has been installed. The “confirmation condition” indicates whether or not to make the user perform confirmation when movement is to be performed, and indicates that the user is caused to perform confirmation when movement is to be performed regarding the user terminal 2 identified by a terminal identifier corresponding to a confirmation condition “1”. On the other hand, it indicates that movement is performed without causing the user to perform confirmation when the movement is to be performed regarding the user terminal 2 identified by a terminal identifier corresponding to a confirmation condition “0”. The “movement condition” is a condition for performing movement using a portal. A movement condition “contact (distance=0)” indicates that contact between an avatar and the portal is a condition. A movement condition “distance <=1” indicates that a condition is that a distance between the avatar and the portal is “1 or less” in a virtual space. A movement condition “−1” indicates that the avatar corresponding to the user terminal 2 identified by the corresponding terminal identifier is not movable using the portal.

In addition, it is assumed that the world storage unit 112 stores a world information management table illustrated in FIG. 10 . The world information management table is a table that manages one or more records having a “world identifier” and “world information”.

In addition, it is assumed that the avatar storage unit 113 stores an avatar information management table illustrated in FIG. 11 . The avatar information management table is a table that manages one or more records having an “avatar identifier” and “avatar information”.

Here, the “portal attribute value” includes a “bidirectional flag”, a “first identifier”, a “second identifier”, “first installation position information”, “second installation position information”, “first movement position information”, “second movement position information”, and a “portal image”.

The “date and time” indicates a date and time when a portal has been installed. The “terminal identifier” indicates the user terminal 2 that has transmitted a portal installation instruction. Regarding the bidirectional flag, “0” indicates a unidirectional portal, and “1” indicates a bidirectional portal. The “portal image” is information specifying an image of the portal, and here, for example, is a file name.

In addition, the portal storage unit 114 stores a portal image illustrated in FIG. 13 . The portal image has an entity of a portal image corresponding to a file name.

In this situation, it is assumed that a world identified by a world identifier “W01” is displayed on the user terminal 2 identified by a terminal identifier “T01”. Further, it is assumed that the user terminal 2 currently displays a screen illustrated in FIG. 14 . Note that it is assumed that world information is transmitted from the information processing device 1 to the user terminal 2, and the user terminal 2 receives and outputs the world information in the process up to the output in FIG. 14 .

Next, it is assumed that a user corresponding to the terminal identifier “T01” has pressed an “install portal” button 1301. It is assumed that the screen of the user terminal 2 then transitions to a screen for determining an installation position of the portal as illustrated in FIG. 15 .

Next, the installation processing unit 132 stores a record having the portal identifier “P58” and the portal information in the portal information management table in FIG. 12 .

Next, the installation processing unit 132 determines whether or not to transmit the portal information to the user terminal 2 corresponding to each of one or more pieces of terminal information managed in the terminal information management table having the structure illustrated in FIG. 9 . Here, the installation processing unit 132 transmits the portal information of “<Bidirectional Flag>0<First Identifier>WO1<Second Identifier>W02<First Installation Position Information>(x₅, y₅, z₅)<Second Movement Position Information>(X₀, Y₀, Z₀)<Portal Image>P01.jpg” and “<Terminal Identifier>T01”, identified by the portal identifier “P58”, to the user terminal 2 corresponding to an avatar movable using the portal. That is, here, the installation processing unit 132 transmits the portal information to each of the user terminals 2 (terminals with terminal identifier “T01, T02, T03, and so on”) corresponding to the terminal information of which the movement condition is not “−1” (not movable) in the terminal information management table. Note that the portal information is not transmitted to the user terminal 2 corresponding to a terminal identifier “T04”.

That is, the deletion determination unit 133 acquires the deletion condition “2 or less”, which is paired with the terminal identifier “T01” corresponding to the installed portal, from the terminal information management table in FIG. 9 .

Next, the deletion determination unit 133 refers to the portal information management table in FIG. 12 and detects that there are three pieces of portal information “P01, P02, and P58” paired with the terminal identifier “T01”. Then, the deletion determination unit 133 determines that the deletion condition “2 or less” is not satisfied. Then, the deletion determination unit 133 determines to delete a portal that has the oldest date and time and has the portal identifier “P01” from among portals identified by the portal identifiers “P01, P02, and P58”.

Next, the deletion processing unit 134 deletes portal information (a record) of the portal identifier “P01” from the portal information management table (FIG. 12 ).

Next, the deletion processing unit 134 transmits a portal deletion instruction including the portal identifier “P01” to the user terminals 2 (terminals with the terminal identifier s“T01, T02, T03, and so on”) corresponding to terminal information other than the movement condition

Next, the terminal reception unit 25 of each of the user terminals 2 having the terminal identifier “T01, T02, T03, and so on” receives portal information of the newly installed portal identifier “P58”. Next, the terminal processing unit 23 of each of the user terminals 2 stores the received portal information in the terminal storage unit 21. Next, the terminal processing unit 23 of each of the user terminals 2 uses the received portal information to configure a portal to be output. The terminal output unit 26 of each of the user terminals 2 outputs the portal to a VR space.

A display example of the new portal in the user terminal 2 is illustrated in FIG. 16 . Reference numeral 1601 in FIG. 16 denotes the newly installed portal.

In addition, the terminal reception unit 25 of each of the user terminals 2 with the terminal identifier “T01, T02, T03, and so on” receives the deletion instruction including the portal identifier “P01” from the terminal reception unit 25. Next, the terminal processing unit 23 of each of the user terminals 2 deletes the portal information corresponding to the received deletion instruction from the terminal storage unit 21. In addition, the terminal processing unit 23 of each of the user terminals 2 configures an output image that hides the portal corresponding to the deletion instruction not to be displayed. Then, the terminal output unit 26 of each of the user terminals 2 hides the portal not to be displayed.

Next, it is assumed that the user with the terminal identifier “T01” operates the user terminal 2 to move the avatar 1701 until coming into contact with the portal (see FIG. 17 ).

Next, the user terminal 2 acquires operation information (here, including position information of the avatar) generated by the operation, and transmits the operation information to the information processing device 1.

Next, the acceptance unit 12 of the information processing device 1 receives the operation information including the position information of the avatar from the user terminal 2 with the terminal identifier “T01”.

Next, the movement determination unit 136 acquires the movement condition “contact (distance=0)” paired with the terminal identifier “T01” from the table of FIG. 9 . Next, the movement determination unit 136 acquires the world identifier “W01” paired with the terminal identifier “T01” from the table in FIG. 9 . Next, the movement determination unit 136 acquires the first installation position information (x₅, y₅, z₅) of the portal information of the portal identifier “P58” paired with the world identifier “W01” and a size of a portal image. Then, the movement determination unit 136 uses the position information of the avatar included in the operation information, the first installation position information (x₅, y₅, z₅), and the size of the portal image to determine that a distance between the avatar and the portal of the portal identifier “P58” is 0. That is, the movement determination unit 136 determines that the movement condition is satisfied.

Next, the confirmation processing unit 135 acquires the confirmation condition “1” paired with the terminal identifier “T01” from the table of FIG. 9 . Then, the confirmation processing unit 135 determines to confirm whether to perform the movement processing. Then, the confirmation processing unit 135 acquires screen information for the confirmation from the storage unit 11, and transmits the screen information to the user terminal 2 that has transmitted the installation instruction.

Next, the user terminal 2 with the terminal identifier “T01” receives the screen information, and outputs a screen illustrated in FIG. 18 using the screen information.

Next, it is assumed that the user has pressed a “move” button 1801 in FIG. 18 .

Then, the terminal acceptance unit 22 accepts a response “move” from the user. Next, the terminal processing unit 23 acquires, for example, a portal identifier or a terminal identifier corresponding to the confirmation information, and configures a response associated with the portal identifier or the terminal identifier. The terminal transmission unit 24 transmits the response associated with the portal identifier or the terminal identifier to the information processing device 1.

Next, the response acceptance unit 122 receives the response “move” from the user terminal 2.

Next, the movement processing unit 137 acquires the second identifier “W02” and the second movement position information (X₀, Y₀, Z₀) of the portal information corresponding to the received operation information from the portal storage unit 114. Next, the movement processing unit 137 performs processing of moving an avatar corresponding to the received operation information to a position specified by the second movement position information (X₀, Y₀, Z₀) in the second VR space identified by the acquired second identifier “W02”. That is, the movement processing unit 137 transmits an avatar identifier “A01”, the second identifier “W02”, and the second movement position information (X₀, Y₀, Z₀) to one or more user terminals 2. Note that the one or more user terminals 2 are the user terminals 2 corresponding to the terminal information managed in FIG. 9 . In addition, the movement processing unit 137 rewrites the world identifier paired with the terminal identifier “T01” in the terminal information management table of FIG. 9 as “W02”.

Then, each of the one or more user terminals 2 receives “<Avatar Identifier>A01<Second Identifier>W02<Second Movement Position Information>(X₀, Y₀, Z₀)”. Such information is information indicating that the avatar of “A01” has moved to the position (X₀, Y₀, Z₀) in the second VR space of “W02”.

Then, in the user terminal 2 outputting the world identifier “W02” and the user terminal 2 with the terminal identifier “T01”, the avatar identified by “A01” is output at the position indicated by the position information (X₀, Y₀, Z₀) in the VR space of “W02”. Note that such an output example is illustrated in FIG. 19 . In FIG. 19 , the avatar that has moved is denoted by 1901.

As described above, a portal, which is an object for an avatar to move between VR spaces, can be installed according to the present embodiment. As a result, each avatar can more easily move between different VR spaces.

In addition, a user can designate an attribute value of a portal to be installed according to the present embodiment. As a result, it is possible to arbitrarily set an installation position of the portal, a VR space as a movement destination, and the like, and it is possible to achieve VR experience with a higher degree of freedom for the user.

In addition, it is possible to set a constraint in installation of a portal according to the present embodiment. As a result, it is possible to suppress unlimited creation of a portal that allows movement to a VR space in which only a specific user can originally participate, or the like.

In addition, a constraint can be provided in a case where an avatar moves using a portal according to the present embodiment. As a result, it is possible to suppress movement to a VR space in which only a specific user can originally participate via the portal.

In addition, a user can confirm whether or not to move when an avatar moves according to the present embodiment. As a result, the user can suppress the avatar from unintentionally moving through the portal.

In addition, a portal can be automatically deleted as appropriate according to the present embodiment. As a result, it is possible to reduce the possibility that a malicious user or the like installs a large number of portals to damage experience of other users in a VR space.

In addition, a bidirectional portal, which is an object for an avatar to move bidirectionally between two VR spaces, can be installed according to the present embodiment. As a result, the movement between VR spaces can be more easily performed since not only unidirectional movement but also bidirectional movement can be performed.

In addition, an installed portal can be reflected in another user terminal 2 according to the present embodiment. As a result, it is possible to more easily move to an arbitrary VR space together with another user.

Note that it has been mainly described that the information processing device 1 is the server that provides various services to one or more user terminals 2 according to the present embodiment. However, it may be configured such that two or more information processing devices 1 communicate with each other in a peer-to-peer (P2P) manner. In such a case, the information processing devices 1 are user terminals used by users.

In addition, the installation processing unit 132, the deletion processing unit 134, and the movement processing unit 137 in the information processing device 1 transmit various types of information to one or more other information processing devices 1. In addition, the acceptance unit 12 in the information processing device 1 receives operation information or information corresponding to the operation information from one or more other information processing devices 1. In addition, transmission processing of various types of information in the information processing device 1 is information output processing.

In addition, the operation in the information processing device 1 constituting the information system B is substantially similar to the operation in the flowchart of FIG. 3 , but the reception in steps S301, S304, S308, and S312 is acceptance of an input from the user. In addition, an output image is output in step S303. In addition, an error message is output in step S406. In addition, portal information is transmitted to one or more other information processing devices 1 in step S413. In addition, a portal is output from the own device in step S413. In addition, the deletion processing unit 134 hides the portal not to be displayed in step S505.
